Application filed February :1,

To all whom 'Ll may concern:

lie it known that I, Gnome l nnn' znn, lessor and royal governmentbuilding-master, a subject of the King of Prussia, 1resi ling; at Hans Neldheim -zin'il iothagerweg, Aixlo-Choppelle, in the Kingdom of Prussia, Empire of Germany, have invented certain new and useful Improvements in l'lzintl Steering-\Vheels for Motor-Vehicles; and I do hereby declare the following to be full, clear, nncl exact description of the invention, such as will enable others skilled in the art to which it uppertnins to make and use the some .llily present invention relates to huntisteering-wheels for inotorw'chicles and er ticularlyto that class thereof, in which the wheel-rim is utilized for operating signaling-devices. To this encl the wheel-rim is made to consist of two rigid preseurerings arranged upon opposite sides of an elastic tnbulzir 1l1l1-l)0(ly suitably connected with an acoustic signaling device, of which rings one is connected with the arms of the steeringwhcel, whereas the other ring, or winged upon the opposite side of seitl tubular hotly, is inevebly arranged.

This invention others the advantages that on the one hand a more powerful and. lasting signal can be given then hitherto it nus been possible to obtain, because the whole volume ot uir contained in said elastic tubular hotly can be elected and utilized for the operation of the signziling-(liwice, and that on the other hand the shocks and vibrations initiated by the vehicle-axle are tlcaclenetl and almostwholly eliminated, because the ring not con ncctetl with the til'nlS of the'steering-wheel can move vertically as well as lihrizontully independent of the ring rigidly cohnectell therewith. The. most prominent practical result gained by this arrangement of ports is, however, that the huntiand linger-loints are to it very high degree protected oi the steeringtnlte long drives over rough rozuls and not fatigue hantland fingei joints. Another very prominent result obtained by my in- Specification of Letters Patent.

vention is that at every moment it is made possible to give a signal without telling one (it the hands oil the steering-wheel, whereby it iloes not matter whether lhis may become necessary on a st night road or when a curve is taken or ecorner rounded, as all that is necessary to give the signal. is to close the grip tighter on the rim of the steeringwhe l. in the accon'ipunying tlrawingtignre l is a side elevation ot' the hand-steeringwhecl, partly shown in section. Fig. *2 is u plan-view oi suitl wheel. 3 ish crosssectiennl view of a modified form of the WliLQl llU'l, wherein the pressure-rings term an integral part of the elastic tubular body. The rim of the steering nheel 1 consists of an elastic hollow ring or tubular belly 2, which can be flattened or compressed between the list rigiil preesuire-rings 3 and. s. One of these pressure'rings, for instance the ring l is connected with the rotatable steering-shaft- 5 by means oi the wheel-arms 6 anti the hub 7, whereas the other ring, for instance the ring fl is niovably arranged on the opposite side of said tubular body and may be nnule to approach the ring l b means of the pressure of the lunuls which grasp the wheel-rim. tion the till contained within said elastic tubular hotly is compressed, and. passes through :1 thin elastic tube 8 to an acoustic signsling-(levice or to another device (notshown} in order to put some into operation. To keep the tube 8 tree of kinks and tangles it is secured to the steering-small; 5 by means of the clip 9. lit howcre'c, not necessary that the first rigid pressure-rings 3 anti 2% shoultl be formed separate from the elastic hollow tubulznwbotly or as (ltlbtlCllZtlLlle ports construction, on the contrary, they may just as well term on integral part thereof as for instance shown in l ijsg'. 3, wherein the elastic tubular body is snp iiosctl to consist of soft. rubber portions 10 and lldirectly comiecteil with or iiusetl to the hard rubber rings 12 until. 123.
